<div dir="ltr">Windows activation, at least for 2008 and below, depend on enough hardware changes to happen. Each HW (of non-pluggable devices) change is a single 'penalty' point - except for NIC (based on MAC address) which is more. 4 or so points - and it requires re-activation.

Most of our virtual machines are Linux, but an increasing number of windows VMs are being integrated into our oVirt DCs.<br>
<br>
We bought tons of windows server licences, and successfully activated them.<br>
<br>
Due to how Windows Product Activation is working, when a windows VM is migrating from a host to another, this product activation is reset, launching a 30 days countdown to auto-shutdown.<br>
<br>
According to this old page :<br>

<a href="https://mazimi.wordpress.com/2007/07/11/getting-around-windows-activation-when-virtualizing/" rel="noreferrer" target="_blank">https://mazimi.wordpress.com/2<wbr>007/07/11/getting-around-windo<wbr>ws-activation-when-virtualizin<wbr>g/</a><br>
<br>
and what I can read in microsoft's 2012 server documentations, I then can re-activate it twice during the next 90 days.<br>
<br>
Assuming I *want* to have *no* control upon the location of the VMs amongst their hosts (I want them to fly freely, confident in the lovely auto-balance scheduler), I understand all this is not the way to go.<br>
<br>
At present, we have 2003, 2008 and 2012 server editions.<br>
the only things I can read about windows 2012 server is related to the commercial aspects (standard licence = 2 VMs, datacenter licencce = infinite # of VMs), but not about this Windows Product Activation trouble.<br>
<br>
How do you deal with this?<br>
Is there a special licence type or something dedicated that would prevent such an uncomfortable situation? (Christmas is near, I favor soft terms.)<br>
